WINDING MACHINE Filed March 26. 1951 2 Sheets-Sheet 2 Qvwewtoq Patented Oct. 4, 1932 UNITED STATES PATENT OFFICE GEORGE W. KIERSIPE, OF FORT WAYNE, INDIANA, ASSIGNOR TO GENERAL CABLE CORPORATION, OF NEW YORK, N. Y., A COBPORATION OF NEW JERSEY' WINDING MACHINE Application filed March 26, 1931. Serial No. 525,418.

This invention relates to coil winding machines'of the type wherein a coil of wire is wound on a coil supporting core which forms apart of the finished coil and to which it is necessary to attach the Wire prior to the winding operation. This has previously been accomplished in various ways, as by nicking or cutting the core at the proper point and securing the wire end thereto by inserting it under the cut portion. Such an operation is necessarily slow and may be inaccurate.

An object of this invention is to provide a coil winding machine constructed and arranged to enable the operator to quickly and accurately secure the wire or wires to the core tube at the beginning of the winding operation.

This and other objects which will be apparent to those skilled in this particular art are accomplished by means of the invention illustrated in the accompanying drawings in which,

Fig. 1 is a perspective View of a coil winding machine for simultaneously winding a plurality of coils, and constructed in accordance with one embodiment of this invention.

Fig. 2 is a transverse sectional view of the machine illustrated in Fig.1, numerous parts being omitted in order to more, clearly lllllS- trate the mechanism of the present invention, and

Fig. 3 is an elevation of a certain detail of construction.

The present invention is illustrated in connection with a multiple, coil winding ma-. chine provided with a spindle 5 adapted to be driven by a suitable driving motor 6 for simultaneously winding a plurality of coils of wire 8 supplied from suitable supply.

spools (not shown).

The spindle 5 is provided with a core tube or former 9 on which'the various coils are wound, the wire 8 being directed to the for-- mer over wire guides 10 mounted on a supporting shaft 11 secured in supporting arms 12 and operable for directing the wire to the former to form the coils 7 as is well known.

Prior to the coil winding operation, the

wires 8 are connected to the core in any suiting operation of the machine.

able way. As hitherto practised, this operation has consumed a considerable amount of I time. The present invention contemplates the provisionof suitable mechanism for assisting and expediting the fastening of the wires to the core.

each frictional gripping member includes adisc '17 secured to the supporting shaft 14 and a co-operating disc 18 yieldingly pressed against the stationary disc by a helical spring 19 located between the yielding disc and a" spring engaging collar 20 secured to the supporting shaft. Each gripping device positioned on the rod 14 directly beneath a point on the core 9 to which one of the wires 8 is to be secured.

In securingthe wires 8 to the core, each wire 8 is led downwardly across the core 9 and positioned between the gripping discs 17, 18 where it is held by the frictional grip thereof. Each wire is placed so as to be held by one of the grippers 13 and when all the wires are properly positioned they can be easily and quickly secured to the core 2 in any desired way such, for example, as by pasting a strip of paper across the wire, by drops of wax applied'to each wire, or any other suitable manner. The wires are then severedbetween the core and the grippers 13 and the severed ends are removed from the grippers, whereupon the machine is ready for the Winding operation. The shaft 16 or other supporting mechanism for the grippers may, if desired, be movable to permit the grippers being lowered or shifted to an out of the way position during the normal wind- Obviously, the'arrangement is, such as to permit the wires being rapidly and accurately secured to the core 2. Although I have described a specific construction embodying one form of this invention, it will be appar cut that various modified arrangements can d be empl oged without departing from the spirit of t e invention or the scope of the appended claims.

I claim as my invention 1 I 5 1. A coil winding machine having in combination a winding spindle, a wire guide for directing wire to said spindle and wire engaging means for holding the wire in position across said spindle to permit said wire my being connectedthereto.

2. A coil winding machine having in combination a support for a coil forming tube and a frictional wife gripping member associated therewith for holding a wire in position on said tube to be connected thereto.

3. A coil winding machine havin in combination a winding spindle and a 'ctional gripping member comprising wire gripping discs for holding a wire in position across said spindle to permit said wire to be-connected thereto, and means for yieldingly pressing said discs together.

4. A coil winding machine having in combination a winding spindle for supporting 85- a coil winding tube, a shaft associated with P said spindle and extending parallel thereto and a plurality of frictional wire grippers located on said shaft for holding wires in ositibn across said spindle to permit them e- '0 'ing'connected thereto.

5. A coil winding machine having in combination a winding spindle, a wire guide for directing wire to said s indie, wire engaging means for holding t "e wire in position across said spindle to permit said wire being connected thereto, and means for movably supporting said wire engaging means to permit said means being moved to inoperative position.

40 In testimony whereof, I have signed my name to this specification this 14th day of March, 1931.
